There should be some conditions where players are not auto-filled
Actually you already can't get auto-filled in promos, why not doing the same with placements ? I know you won't play placement games most of the time but it's still some of the most important games you'll play each season Like seriously, I played adc for the first time of my life two days ago in my placements thanks to auto-fill
Also, auto-fill is supposed to reduce the queue time, so if the queue time have been really long or like a lot of people dodged this makes no sense to be still auto-filled I mean there was a time I got 8 dodges in a row (what even is that cmon) and i got auto-filled it was the worst feeling ever (and i'm not even the one that care the most about being auto-filled or not since i like to try out new things but it still bothers me)
